BACKGROUND

As the computer gaming market continues to grow, improvements to existing gaming systems as well as new systems are introduced. One computer gaming device recently introduced to the market is the KINECT sensor device for use with the XBOX 360 video game platform, both produced by Microsoft Corporation. KINECT is a trademark of Microsoft Corporation, Redmond, Wash. XBOX 360 is a registered trademark of Microsoft Corporation, Redmond, Wash. The KINECT sensor device allows a user to control and interact with the XBOX 360 through the use of gestures and spoken commands, without the need to touch a game controller. The KINECT sensor device uses an infrared depth sensor for three-dimensional motion capture of a user, and the user must remain within a certain range of distance from the sensor device, depending on the user's body height.

In addition to the computer gaming market continuing to grow in popularity, with the increasing transportability and the decreasing costs of video game systems and video display devices for use therewith, it has become common to play video games in a variety of locations other than one's living room. For example, a user may wish to play a video game in a small space, such as in an office, a vehicle, or simply a small room, where physical constraints require that the user be in close proximity to a sensor device of the video game system. As such, for use of some systems including a video game sensor device such as the KINECT, it is desirable to be able to adjust a playing distance between the user and the video game sensor device.

Accordingly, the drawings and description are to be regarded as illustrative in nature, rather than restrictive. Further, terms such as “upper,” “lower,” “front,” “back,” “top,” “bottom,” “upward,” and “downward” are used herein for the purpose of more clearly describing the location and/or orientation of components or features relative to others, as shown in the drawings, for example. However, the use of such terms is not intended or to be regarded as limiting the use of the invention to any particular position or orientation.

With reference to FIGS. 1-4, a video game sensor device 10 according to one exemplary embodiment of the present invention includes a lens apparatus 50. In one embodiment, the lens apparatus 50 is movable between an adjusting position, as shown in FIGS. 1-4, in which at least one lens of the lens apparatus 50 covers at least one of an infrared light emitter 42, an infrared light receiver 44, and a camera 45 of the video game sensor device 10, and a non-adjusting position (see FIGS. 5-8) in which the lens apparatus 50 does not cover the infrared light emitter 42, the infrared light receiver 44, and the camera 45.

With reference to FIGS. 5-8, the video game sensor device 10 includes a casing 20 which houses the infrared light emitter 42, the infrared light receiver 44, and the camera 45. In one embodiment, the casing 20 has a generally rectangular or trapezoidal prismatic shape including a front side 22, a top side 24, a rear side 26, and a bottom side 28. The infrared light emitter 42, the infrared light receiver 44, and the camera 45, in one embodiment, are facing the front side 22, and the front side 22 may have one or more openings exposing the infrared light emitter 42, the infrared light receiver 44, and the camera 45. Further, in one embodiment, the casing 20 of the video game sensor device 10 includes a support post 30 coupled to the bottom side 28 for supporting the video game sensor device 10 on a support base, for example.

With further reference to FIGS. 1-4, the lens apparatus 50 includes a body portion including a front side 52, a top side 54, a rear side 56, and a bottom side 58 that are spaced apart from one another and configured similarly to the respective front side 22, top side 24, rear side 26, and bottom side 28 of the casing 20 and are mounted thereto. The body portion may be made of a thermoplastic material (e.g., SABIC PC/ABS C6200) or any other suitable material. The lens apparatus 50 further includes a first lens 62, a second lens 64, and, in one embodiment, a third lens 65 coupled to the front side 52. In one embodiment, the first lens 62, the second lens 64, and the third lens 65 are configured to cover the infrared light emitter 42, the infrared light receiver 44, and the camera 45, respectively, for adjusting a sensing distance of the video game sensor device 10. Each of the first lens 62, the second lens 64, and the third lens 65 has a magnification, and, in one embodiment, the magnification of each is the same. The magnification may be selected depending on the amount by which the sensing distance of the video game sensor device 10 is desired to be adjusted. For example, where it is desired that the sensing distance of the video game sensor device 10 be adjusted to be less (e.g., for use in a small room), the first lens 62, the second lens 64, and the third lens 65 may have a magnification of less than 1×. For example, in one embodiment, the first lens 62, the second lens 64, and the third lens 65 may have a magnification of about 0.5× to about 0.7×. In one embodiment, the first lens 62, the second lens 64, and the third lens 65 have a magnification of about 0.6×. However, the present invention is not limited thereto and, in other embodiments, the first lens 62, the second lens 64, and the third lens 65 may have any other suitable magnification. Further, in another embodiment, if it is desired that the sensing distance of the video game sensor device 10 be adjusted to be greater, the first lens 62, the second lens 64, and the third lens 65 may have a magnification of greater than 1×. Further, in one embodiment, the first lens 62, the second lens 64, and the third lens 65 may have a magnification that is adjustable. Further, in one embodiment, the first lens 62, the second lens 64, and the third lens 65 may be coated with a coating material that is configured to block non-infrared light.

The lens apparatus 50 is coupled (e.g., removably attached) to a video game sensor device and, in one embodiment, includes a clip portion 70. The clip portion 70 may be configured as a pair of opposing hooks 72 having an opening 74 therebetween receiving the support post 30 therein. The hooks 72 may be elastically deformable for receiving the support post therebetween and for clamping around the support post 30 for attachment of the lens apparatus 50 to the support post 30. However, embodiments of the present invention are not limited to the clip portion 70 described above and shown in the drawings. Rather, in other embodiments, the lens apparatus 50 may include any other suitable clip portion or other attachment device or method, or combination thereof, for removably or permanently attaching the lens apparatus 50 to the casing 20. Further, in one embodiment, the casing 20 and the lens apparatus 50 may be integrally manufactured as a unit.

While, in one embodiment, the casing 20 and the lens apparatus 50 each have four sides forming a generally rectangular cross-sectional shaped body, the present invention is not limited thereto. That is, in other embodiments, one or both of the casing 20 or the lens apparatus 50 may have any suitable shape or number of sides for coupling to one another. Further, in one embodiment the casing 20, the infrared light emitter 42, the infrared light receiver 44, and the camera 45 may be configured the same or similarly to the KINECT, as depicted in FIGS. 1-8, but in other embodiments, may have configurations different from that of the KINECT.

In one embodiment, as shown in FIGS. 4 and 8, for example, the front side 52 is connected to the top side 54, the top side 54 is rotatably connected to the rear side 56 via a hinge 80, and the rear side 56 is connected to the bottom side 58. In one embodiment, the top side 54 is rotatable together with the first lens 62, the second lens 64, and the third lens 65 relative to the rear side 56 and the casing 20 via the hinge 80 for moving the first lens 62, the second lens 64, and the third lens 65 between an adjusting position (see FIGS. 1-4) in which the first lens 62, the second lens 64, and the third lens 65 cover the infrared light emitter 42, the infrared light receiver 44, and the camera 45, and a non-adjusting position (see FIGS. 5-8) in which the first lens 62, the second lens 64, and the third lens 65 do not cover the infrared light emitter 42, the infrared light receiver 44, and the camera 45. In other embodiments, the hinge 80 may be located between the front side 52 and the top side 54 or between the rear side 56 and the bottom side 58. In another embodiment, more than one pair of sides may be rotatably connected. Further, in another embodiment, the hinge 80 may be absent, and the lens apparatus 50 may be configured for at least one of the first lens 62, the second lens 64, and the third lens 65 to cover at least one of the infrared light emitter 42, the infrared light receiver 44, and the camera 45 by any other device or method, such as the first lens 62, the second lens 64, and the third lens 65 being slidably movable relative to the infrared light emitter 42, the infrared light receiver 44, and the camera 45.

With reference to FIG. 9, according to one embodiment, the first lens 62 and the second lens 64 of the lens apparatus 50 are oriented at an angle relative to each other such that respective center axes 66 and 68 of the first lens 62 and the second lens 64 cross each other at a convergence point CP. That is, both the first lens 62 and the second lens 64 aim at the convergence point CP. In one embodiment, the center axis 66 of the first lens 62 is oriented at an angle α with respect to an axis perpendicular to the front side 22 of the casing 20 and/or an axis perpendicular to the front side 52 of the lens apparatus 50. Similarly, the center axis 68 of the second lens 64 is oriented at an angle β with respect to an axis perpendicular to the front side 22 of the casing 20 and/or an axis perpendicular to the front side 52 of the lens apparatus 50. In one embodiment, the angles α and β are equal or substantially equal. However, embodiments of the present invention are not limited thereto, and in other embodiments, the angles α and β may be different. In one embodiment, the angles α and β may each be about 1.1 degrees. In one embodiment, respective edges of the first lens 62 (see, for example, edge 162 a shown in FIG. 19) and the second lens 64 which abut the front side 22 of the casing 20 are beveled in order to provide the angles α and β. Also, in one embodiment, the respective center axes 66 and 68 of the first lens 62 and the second lens 64 are substantially horizontal, such that the convergence point CP is at substantially a same height as the first lens 62 and the second lens 64. Further, in one embodiment, the first lens 62 and the second lens 64 may be stationary, or fixed, relative to each other, and the angles α and β are constant. Alternatively, in another embodiment, the orientation of one or both of the first lens 62 and the second lens 64 may be moveable (i.e. the angles α and β are variable), such as for adjusting a distance from the lens accessory 50 to the convergence point CP. In another embodiment, the respective center axes 66 and 68 of the first lens 62 and the second lens 64 may not cross each other at a convergence point CP but, rather, each of the first lens 62 and the second lens 64 may be oriented parallel to an axis perpendicular to the front side 22 of the casing 20 and/or an axis perpendicular to the front side 52 of the lens apparatus 50. That is, in one embodiment, each of the angles α and β is 0 degrees.

With reference to FIGS. 10 and 11, a lens accessory 100 according to an embodiment of the present invention is mountable, attachable, or otherwise useable with a video game sensor device for adjusting a sensing distance of the video game sensor device. The lens accessory 100 may be configured as lens goggles mountable on a video game sensor device, such as the KINECT or any other suitable video game sensor device. Furthermore, the lens accessory 100, in one embodiment, as shown in FIGS. 10 and 11, has a same or substantially same configuration as that of the lens apparatus 50 described above and shown in FIGS. 1-9 as a component of the video game sensor device 10. However, embodiments of the present invention are not limited thereto, and in other embodiments, the lens accessory 100 may have any other suitable configuration for covering a video game sensor device and adjusting a sensing distance thereof.

In one embodiment, as shown in FIGS. 10 and 11, the lens accessory 100 has substantially the same configuration as the lens apparatus 50 described above.

The body portion may be made of a thermoplastic material (e.g., SABIC PC/ABS C6200) or any other suitable material. The first lens 62, the second lens 64, and the third lens 65 are configured to cover an infrared light emitter, an infrared light receiver, and a camera, respectively, of a video game sensor device for adjusting a sensing distance of the video game sensor device. Also, as described above with respect to the lens apparatus 50, each of the first lens 62, the second lens 64, and the third lens 65 of the lens accessory may have a magnification that is the same, and in one embodiment, for example, the first lens 62, the second lens 64, and the third lens 65 may have a magnification of about 0.5× to about 0.7×, such as a magnification of about 0.6×. However, in other embodiments, the magnification may be any other desired amount depending on a degree to which the user desires to adjust a sensing distance of a video game sensor device. In one embodiment, the first lens 62, the second lens 64, and the third lens 65 may have a magnification that is adjustable. Further, in one embodiment, the first lens 62, the second lens 64, and the third lens 65 may be coated with a coating material that is configured to block non-infrared light.

The lens accessory 100 is coupleable (e.g., removably attachable) to a video game sensor device and, in one embodiment, includes the clip portion 70. As shown in further detail in FIG. 11, the clip portion 70 may be configured as a pair of opposing hooks 72 having an opening 74 therebetween for receiving a support post of a video game sensor device therein. The hooks 72 may be elastically deformable for receiving the support post therebetween and for clamping around the support post for attachment of the lens accessory 100 to the support post. However, embodiments of the present invention are not limited to the clip portion 70 described above and shown in the drawings. Rather, in other embodiments, the lens accessory 100 may include any other suitable clip portion or other attachment device or method, or combination thereof, for removably or permanently attaching the lens accessory 100 to a video game sensor device.

While in one embodiment the lens accessory 100 has four sides forming a generally rectangular cross-sectional shaped body, the present invention is not limited thereto. That is, in other embodiments, the lens accessory 100 may have any suitable shape or number of sides for coupling with any of various video game sensor devices, which may have configurations different from that of the KINECT, the general shape of which is depicted in FIGS. 1-9 as the housing 20 of the video game sensor device 10. Further, in one embodiment, as shown in the drawings, the front side 52 is connected to the top side 54, the top side 54 is rotatably connected to the rear side 56 via the hinge 80, and the rear side 56 is connected to the bottom side 58. However, in other embodiments, the hinge 80 may be located between the front side 52 and the top side 54 or between the rear side 56 and the bottom side 58. In another embodiment, more than one pair of sides may be rotatably connected. Further, in another embodiment, the hinge 80 may be absent, and the lens accessory 100 may be configured for at least one of the first lens 62, the second lens 64, and the third lens 65 to cover at least one of an infrared light emitter, an infrared light receiver, and a camera of a video game sensor device by any other device or method, such as the first lens 62, the second lens 64, and the third lens 65 being slidably movable relative to the infrared light emitter, the infrared light receiver, and the camera.

With reference to FIGS. 12-17, a video game sensor device 110 according to another exemplary embodiment of the present invention includes a lens apparatus 150. In one embodiment, the lens apparatus 150 is movable or detachably coupleable to a casing 120 of the video game sensor device 110 between an adjusting position, as shown in FIG. 12, in which at least one lens of the lens apparatus 150 covers at least one of an infrared light emitter 142, an infrared light receiver 144, and a camera 145 of the video game sensor device 110, and a non-adjusting position in which the lens apparatus 150 does not cover the infrared light emitter 142, the infrared light receiver 144, and the camera 145, such as where the lens apparatus 150 is uncoupled from the casing 120. FIG. 13 shows the lens apparatus 150 partially uncoupled from the casing 120. That is, in FIG. 13, a front portion of the lens apparatus 150 is coupled to the casing 120, but a rear portion is detached, or unclipped, from the casing 120.

With reference to FIGS. 12-17, the video game sensor device 110 includes a casing 120 which houses the infrared light emitter 142, the infrared light receiver 144, and the camera 145. In one embodiment, the casing 120 has a generally rectangular or trapezoidal prismatic shape including a front side 122, a top side 124, a rear side 126, and a bottom side 128. The infrared light emitter 142, the infrared light receiver 144, and the camera 145, in one embodiment, are facing the front side 122, and the front side 122 has one or more openings exposing the infrared light emitter 142, the infrared light receiver 144, and the camera 145. Further, in one embodiment, the casing 120 of the video game sensor device 110 includes a support post 130 coupled to the bottom side 128 for supporting the video game sensor device 110 on a support base, for example.

The lens apparatus 150 includes a body portion including a front side 152, a top side 154, a rear side 156, and a bottom side 158 that are spaced apart from one another and configured similarly to the respective front side 122, top side 124, rear side 126, and bottom side 128 of the casing 120 and are mounted thereto. The lens apparatus 150 further includes a first lens 162, a second lens 164, and, in one embodiment, a third lens 165 coupled to the front side 152. In one embodiment, the first lens 162, the second lens 164, and the third lens 165 are configured to cover the infrared light emitter 142, the infrared light receiver 144, and the camera 145, respectively, for adjusting a sensing distance of the video game sensor device 110. Each of the first lens 162, the second lens 164, and the third lens 165 has a magnification, and, in one embodiment, the magnification of each is the same. The magnification may be selected depending on the amount by which the sensing distance of the video game sensor device 110 is desired to be adjusted. For example, where it is desired that the sensing distance of the video game sensor device 110 be adjusted to a shorter distance (e.g., for use in a small room), the first lens 162, the second lens 164, and the third lens 165 may have a magnification of less than 1×.

Further, a lens according to other embodiments of the present invention may be made up of a single lens element or more than two lens elements. In one embodiment, the lens 264′ may cover an infrared light receiver of a video game sensor device. However, a lens covering an infrared light receiver or a camera of a video game sensor device may have a same or similar configuration.

With reference to FIG. 22, a method 300 of adjusting a sensing distance of a video game sensor device, according to one embodiment of the present invention, is shown. The method 300 is described herein with respect to the video game sensor devices 10, 110 described herein; however, the method 300, or at least some of the tasks thereof, may also be performed using a video game sensor device or a lens accessory for a video game sensor device according to another embodiment, such as the lens accessory 100 or the lens accessory 200 described herein.

In one embodiment, the method 300 includes a task 310 of providing at least one lens. In one embodiment, the at least one lens may include the first lens 62, 162 and the second lens 64, 164 of the video game sensor device 10, 110 or the lens accessory 100, 200 described above. In one embodiment, the at least one lens further includes the third lens 65, 165 described above for covering the camera 45, 145. The method 300, in one embodiment, further includes a task 320 of coating the at least one lens with any suitable coating material for blocking non-infrared light.

The method 300, in one embodiment, includes a task 330 of coupling the at least one lens to a video game sensor device. As described above, the lens apparatus 50, 150, in one embodiment, is removably attachable to the casing 20, 120 of the video game sensor device 10, 110 via a clip portion 70, 170. Similarly, the lens accessories 100, 200 described above may include the clip portion 70, 170 configured to removably attach the lens accessory 100, 200 to a video game sensor device by clipping onto a support post or a casing of the video game sensor device. However, the task 330 of coupling the at least one lens to a video game sensor device is not limited thereto. Rather, the at least one lens may be coupled to a video game sensor device by any other suitable device or method and, moreover, may be removably or permanently coupled by either a user or during a manufacturing process. For example, in one embodiment, the lens apparatus 50, 150 may be attached to, or integrally formed with, the casing 20, 120 of the video game sensor device 10, 110 during a manufacturing process.

In one embodiment, the method 300 further includes a task 340 of rotating the at least one lens. That is, in one embodiment, the first lens 62, 162, the second lens 64, 164, and the third lens 65, 165 may be rotated about an axis of rotation, such as via the hinge 80, relative to the video game sensor device for moving the first lens 62, 162, the second lens 64, 164, and the third lens 65, 165 between a non-adjusting position in which the first lens 62, 162, the second lens 64, 164, and the third lens 65, 165 do not cover the infrared light emitter 42, 142, the infrared light receiver 44, 144, and the camera 45, 145, respectively, and an adjusting position in which the first lens 62, 162, the second lens 64, 164, and the third lens 65, 165 cover the infrared light emitter 42, 142, the infrared light receiver 44, 144, and the camera 45, 145, respectively, for adjusting a sensing distance of the video game sensor device.

The method 300 may further include a task 350 of covering an infrared light emitter and an infrared light receiver with the at least one lens. In one embodiment, the infrared light emitter 42, 142 and the infrared light receiver 44, 144 are covered with the first lens 62, 162 and the second lens 64, 164. In one embodiment, when the first lens 62, 162 and the second lens 64, 164 are rotated or otherwise moved to the adjusting position, the first lens 62, 162 and the second lens 64, 164 will cover the infrared light emitter 42, 142 and the infrared light receiver 44, 144, respectively, for adjusting a sensing distance of the video game sensor device. In other embodiments, the infrared light emitter and an infrared light receiver may be covered with the at least one lens by any other suitable device or method. For example, in one embodiment, the first lens 62 and the second lens 64 may be moved to cover the infrared light emitter 42, 142 and the infrared light receiver 44, 144 by translation (e.g., by a sliding motion), rather than by rotation about an axis. Further, in another embodiment, the infrared light emitter 42, 142 and the infrared light receiver 44, 144 may be moved to a position where they are covered by the first lens 62, 162 and the second lens 64, 164, while the first lens 62, 162 and the second lens 64, 164 are maintained in a stationary location.

The method 300 may further include a task 360 of at least partially inserting the at least one lens into at least one cavity of the video game sensor device. In one embodiment, the second lens 164 is moved from a position outside the cavity 148 adjacent the infrared light receiver 144 (see FIG. 16) to a position in which the second lens 164 is partially inserted in the cavity 148 (see FIGS. 15 and 17). Similarly, in one embodiment, the first lens 162 is partially inserted into the cavity 146 adjacent the infrared light emitter 142, and the third lens 165 is partially inserted in the cavity 149 adjacent the camera 145.

Further, in one embodiment, the method 300 includes a task 365 of biasing the at least one lens toward the at least one cavity of the video game sensor device using a biasing mechanism. In one embodiment, the biasing mechanism 172 is a compression spring. The biasing mechanism 172 pushes against a rib of the at least one lens, such as the rib 164 a of the second lens 164 (see, e.g., FIG. 17) and thereby pushes the lens into the cavity of the casing 120 and provides a retention force for holding the lens in the cavity. In one embodiment, the first lens 162 is biased toward the cavity 146 adjacent the infrared light emitter 142, the second lens 164 is biased toward the cavity 148 adjacent the infrared light receiver 144, and the third lens 165 is biased toward the cavity 149 adjacent the camera 145. In other embodiments, the biasing mechanism 172 may include any other suitable biasing mechanism instead of or in addition to a compression spring.

Further, in one embodiment, the method 300 includes a task 370 of covering the camera 45, 145 with the third lens 65, 165. Similarly, in one embodiment, the third lens 65, 165 covers the camera 45, 145 when the third lens 65, 165 is rotated or otherwise moved to the adjusting position, or when the lens apparatus 50, 150 is clipped onto the casing 20, 120 of the video game sensor device 10, 110.

In one embodiment, the method 300 further includes a task 380 of adjusting a magnification of the at least one lens. As described above, the first lens 62, 162, the second lens 64, 164, and the third lens 65, 165 may have an adjustable magnification. Further, the magnification may be adjustable without removing the lens apparatus 50, 150 or the lens accessory 100, 200 from the video game sensor device. As such, the sensing distance of the video game sensor device may be quickly and easily changed so that a user may play the video game while standing at any of various distances from the video game sensor device.

The method 300, in one embodiment, further includes a task 390 of uncovering the infrared light emitter and the infrared light receiver. In one embodiment, the infrared light emitter 42, 142 and the infrared light receiver 44, 144 may be uncovered by moving the first lens 62, 162 and the second lens 64, 164 from the adjusting position to the non-adjusting position. Further, the task 390 may further include uncovering the camera 45, 145 by moving the third lens 65, 165 from the adjusting position to the non-adjusting position.

While in one embodiment, the method 300 of adjusting a sensing distance of a video game sensor device may include each of the tasks described above and shown in FIG. 22, in other embodiments of the present invention, in a method of adjusting a sensing distance of a video game sensor device, one or more of the tasks described above and shown in FIG. 22 may be absent and/or additional tasks may be performed. Further, in the method 300 of adjusting a sensing distance of a video game sensor device according to one embodiment, the tasks may be performed in the order depicted in FIG. 22. However, in a method of adjusting a sensing distance of a video game sensor device according to other embodiments of the present invention, the tasks described above and shown in FIG. 22 may be performed in any other suitable sequence.

An application of embodiments of the present invention that have been described above will now be described with respect to FIGS. 23A through 24D. FIG. 23A is a schematic diagram showing a user 400 at a position B relative to a conventional video game sensor device 402, such as the KINECT, that does not have a lens accessory of the present invention coupled thereto. FIG. 23B is a schematic diagram showing an image 405 captured by the conventional video game sensor device 402 when the user 400 is at the position B. The image 405 includes the entire body of the user 400. FIG. 23C is a schematic diagram showing the user 400 at a position A relative to the conventional video game sensor device 402, in which the position A is at a distance from the conventional video game sensor device 402 less than that of the position B. For example, the position A may be 4 feet from the conventional video game sensor device 402, and the position B may be 7 feet from the conventional video game sensor device 402. Further, the user 400 may be 6 feet tall. FIG. 23D is a schematic diagram showing an image 406 captured by the conventional video game sensor device 402 when the user 400 is at the position A. The image 406 does not include the head and lower legs of the user 400. Therefore, in order to properly use the conventional video game sensor device 402, the user 400 must be at the position B.

FIG. 24A is a schematic diagram showing a user 410 at a position A relative to a video game sensor device 412 or a video game sensor device having a lens accessory according to embodiments of the present invention. The position A corresponds to the position A shown in FIGS. 23C and 23D.

As depicted in FIG. 24B, the image 416 includes the entire body of the user 410. As such, the user 410 may use the video game sensor device 412 according to embodiments of the present invention at the position A, and the image 416 includes the entire body of the user 410, unlike the image 406 captured by the conventional video game sensor device 402 shown in FIG. 23D. FIG. 24C is a schematic diagram showing the user 410 at a position B relative to the video game sensor device 412, where the position B corresponds to the position B shown in FIGS. 23A and 23B. FIG. 24D is a schematic diagram showing an image 418 captured by the video game sensor device 412 when the user 410 is at the position B. As depicted, the image 418 appears smaller than the image 416 but also includes the entire body of the user 410.

Although the drawings and accompanying description illustrate some exemplary embodiments of a video game sensor device and a lens accessory for a video game sensor device, it will be apparent that the novel aspects of the present invention may also be carried out by utilizing alternative structures, sizes, shapes, and/or materials in embodiments of the present invention.
